2. Description of Related Art

The AI system is a computer system which implements intelligence of a human level, and is a system in which a machine learns and decides by itself to get smart, unlike previous rules-based smart system. As the AI system is used more and more, a recognition rate is improved and thus, a taste of a user is understood more accurately. Accordingly, the previous rules-based smart system is gradually replaced with a deep-learning AI system.

The AI technology includes a machine learning (deep learning) and element technologies using the machine learning.

The machine learning is an algorithm technology which classifies and learns features of input data by itself. The element technology is a technique that uses a machine learning algorithm such as deep learning and the like, which includes technical fields including linguistic understanding, visual understanding, inference/prediction, knowledge expression, motion control and the like.

Various fields to which the AI technology is applied are as follows. The linguistic understanding is a technique of recognizing a language and character of human and applying and processing the same, which includes natural language processing, machine translation, conversation system, question and answer, voice recognition and synthesis and the like. The visual understanding is a technique of recognizing and processing an object just like a human sight, which includes object recognition, object tracking, image search, human recognition, scene understanding, space understanding, image improvement and the like. The inference prediction is a technique of determining information and make a logical inference and prediction, which includes knowledge/probability-based inference, optimization prediction, preference-based plan, recommendation and the like. The knowledge expression is a technique of performing automation processing with respect to experience information of human with knowledge data, which includes knowledge construction (data generation/classification), knowledge management (data usage) and the like. The motion control is a technique of controlling an autonomous driving of a vehicle and movement of a robot, which includes a motion control (navigation, collision, drive), manipulation control (behavioral control) and the like.

In recent years, an electronic device in which various forms of AI secretary functions are provided has been distributed. However, a related art AI secretary service function is provided to a user mainly through voice recognition. For example, when a user asks a simple question “How is the weather today?” an electronic device provides information such as “Tomorrow, Yongin-si, Suji-gu, there will be a lot of clouds in the sky. It is expected that the highest temperature is 28 degrees and the lowest temperature is 15 degrees,” through voice. Accordingly, when information is provided through voice, even if the user wants to obtain simple information, there is an inconvenience to listen to a voice for a long time.

The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

The service providing system 100 according to the disclosure may be implemented as an electronic device 100, an external device 200, and a server, but is not limited thereto. The service providing system 100 may, of course, be implemented as an independent apparatus which is capable of carrying out all functions of the electronic device 100, the external device 200 and the server 300.

The configurations and operations of the electronic device 100, the external device 200, and the server 300 according to an example embodiment will be described in greater detail below.

FIG. 2A is a block diagram illustrating an example configuration of an electronic apparatus according to an embodiment of the disclosure.

Referring to FIG. 2A, the electronic device 100 includes a display 110, a sensor 120, and a processor 130.

The display 110 is a configuration for displaying various images. In more detail, the display 110 may display a graphic object corresponding a user's position and change a graphic object so that feedback relating to a user interaction is provided.

The sensor 120 is a configuration for detecting various information. In more detail, the sensor 120 may detect a user's position. The sensor 120 may include a first camera and a second camera. In this regard, the first camera may be disposed in the direction of a display, and the second camera may be disposed in the opposite direction to the first camera. The first camera may detect a user's position, and the second camera may acquire a background image.

The processor 130 controls an overall operation of the electronic device 100. In more detail, when an interaction mode that operates according to a user's interaction is initiated, the processor 130 may control the display 110 to display a graphic object at a position corresponding to the user's position detected through the sensor 120. When a user's interaction is input after the interaction mode is initiated, the processor 130 may change a graphic object to correspond to the user's interaction and control the display 110 to provide feedback relating to the user's interaction.

When the interaction mode is initiated, the processor 130 may activate the first camera and detect a user's position acquired by the camera. The processor 130 may control the display 120 to display a graphic object based on the acquired user's position. For example, when the user's position is a left side of the electronic device 100, the processor 130 may display a graphic object on the right side of the display 110. In addition, when the user's position is a right side of the electronic device 100, the processor 130 may display a graphic object on the left side of the display 110.

In addition, the processor 130 may activate the second camera and acquire a background image. The processor 130 may display a graphic object based on the acquired background image. In more detail, when the first camera and the second camera photograph the opposite directions, a background image acquired through the second camera may be a background image in the same direction as the background that the user views. For example, when a sofa is present in a background viewed by the user and the background image acquired by the second camera, the processor 130 may display a graphic object so that a graphic object realized as a character is positioned near the sofa.

If various conditions are met, the processor 130 may initiate the interaction mode. In an example embodiment, when the electronic device 100 is coupled with the external device 200, the processor 130 may initiate the interaction mode. In more detail, in a case in which the external device 200 includes a configuration for wireless charging, when the wireless charging is initiated, the processor 130 may initiate the interaction mode and control the display 110 to display a graphic object. When the electronic device 100 and the external device 200 are docked with each other, the processor 130 may initiate the interaction mode and control the display 10 to display a graphic object.

In another example embodiment, after the wireless charging is initiated or docking is complete, when a particular user command is input, the processor 130 may initiate the interaction mode. That is, according to an example embodiment, when the wireless charging is initiated or the electronic device 100 is docked with the external electronic device 200, the processor 130 may control the electronic device 100 to be in a standby mode state in which a user command is input to execute the interaction mode. In the standby mode state, when a user command is input, the processor 130 may initiate the interaction mode. In this regard, the user command may be a voice command of the user or a motion command of the user. For example, when a predetermined voice command, such as “Hey, buddy” or a predetermined motion command to wave hand left to right is input, the processor 130 may initiate the interaction mode.

In this regard, the interaction mode may be a voice recognition mode to operate according to a user voice. When the interaction mode is a voice recognition mode, the processor 130 may constantly change a graphic object to correspond to an input process and processing process of an input user voice. In addition, the interaction mode may be a motion recognition mode to operate according to a user's motion. When the interaction mode is a motion recognition mode, the processor 130 may constantly change a graphic object to correspond to an input process and processing process of a user's motion.

When the interaction mode is executed, the processor 130 may receive various user interactions and provide feedback corresponding to the user interactions.

The user's interaction according to an example embodiment may be in various forms. For example, the user's interaction may be a user input using a user's voice, a user's gesture, or a remote control device.

When the user's interaction is a user's voice, the electronic device 100 may analyze the user's voice and carry out a command corresponding to the user's voice. In this regard, a command corresponding to the user's voice may be a command of a pre-stored form. For example, a power-on/power-off function corresponding to a supervised, such as “turn on power” and “turn off power” is pre-stored, the electronic device 100 may determine a supervised corresponding to the user's voice and carry out a function corresponding to the determined instruction. However, the example is not limited thereto, and even if a user voice that is not a user voice corresponding to a pre-stored instruction is input, the electronic device 100 may analyze the user's voice and determine a user's intention, and carry out a function corresponding to the user's intention. In this regard, the identification of the user's intention may be carried out in the electronic device 100, but may, of course, be carried out in the server 300 as will be described later.

When the user's interaction is a user's gesture, the electronic device 100 may carry out a function corresponding to the user's gesture. In an example embodiment, the function corresponding to the user's gesture may include a gesture indicating start of the gesture, a gesture for selecting a particular item or a particular user interface (UI), a gesture for dragging a particular area, a gesture for rotating a particular area, a gesture for translating a particular area, and a gesture for swipe operation. In addition to a gesture for carrying out the particular function described above, the user's interaction may include a gesture for communing with a graphic object displayed on the display 110. For example, the user's interaction may be a gesture to pat a graphic object or a gesture to slap high-fives with a graphic object.

FIG. 2B is a block diagram of a detailed configuration of an electronic device, according to an embodiment of the disclosure.

Referring to FIG. 2B, the electronic device 100 may further include not only a display 110, a sensor 120 and a processor 130, but also a communicator 140, a memory 150, an audio processor 160, an audio output unit 170, and an input unit 180.

The display 110 may display various screens as described above. The display 110 may be implemented as a display panel of various shapes. For example, the display panel may be implemented with various display technologies such as liquid crystal display (LCD), organic light emitting diode (OLED), active-matrix organic light-emitting diode (AM-OLED), liquid crystal on silicon (LCOS), or digital light processing (DLP).

The display 110 may be implemented in a form of a flexible display form and may be connected to at least one of a front area, a side area, and a rear area of the electronic device 100. Due to a substrate as thin and flexible as a paper sheet, the flexible display may have such characteristic that it can be bent, curved, or rolled without being damaged. The flexible display may be manufactured using a plastic substrate as well as a glass substrate which is generally used. When the plastic substrate is used, a low temperature manufacturing process may be used instead of an existing manufacturing process to avoid damage on the substrate. Also, a glass substrate enclosing a flexible liquid crystal may be replaced with a plastic film so as to give flexibility enabling folding and unfolding. Such a flexible display may be thin, light and even resistant to an impact or a shock, and can be twisted or bended. The flexible display also may be embodied in various forms.

For example, the camera 121 may include at least one image sensor, a lens, an image signal processor (ISP), or a flash (e.g., light emitting diode (LED), xenon lamp, and the like), and may include a plurality of cameras 121. In more detail, the camera 121 may include a first camera and a second camera. In this regard, the first camera may be disposed in the direction of a display, and the second camera may be disposed in the opposite direction to the first camera. The first camera may detect a user's position, and the second camera may acquire a background image.

The acceleration sensor 122 is a configuration for measuring an acceleration of the electronic device 100, and the gyro sensor 123 is a sensor which recognizes a 6 axle direction by exerting rotation to the previous acceleration sensor so that a more elaborate and precise operation can be recognized.

The illumination sensor 124 is a sensor which is capable of detecting a peripheral illumination, and may be used to adjust a brightness of the display 110 according to the peripheral illumination. The humidity sensor 125 is a sensor which is capable of detecting peripheral humidity, and may be used to provide peripheral environment information.

The infrared ray sensor 126 and the ultrasonic sensor 127 are a sensor which is capable of detecting a distance from an external object. In an example embodiment, the processor 130 may determine a user's position by using the infrared ray sensor 126 or the ultrasonic sensor 127 instead of the first camera.

The above-described various types of sensors may, of course, be added or omitted as necessary.

The communicator 140 may communicate with an external device. In particular, the communicator 140 may include various communication chips such as a Wi-Fi chip 141, a Bluetooth chip 142, a wireless communication chip 143, and a near field communication (NFC) chip 144. The Wi-Fi chip 141, the Bluetooth chip 142, and the NFC chip 144 communicate using local area network (LAN), Wi-Fi, Bluetooth, and NFC, respectively. In the case of using the Wi-Fi chip 141 or the Bluetooth chip 142, various connection information such as service set identifier (SSID) and session key may be transmitted and received first, and various information may be transmitted and received after communication is built by using it. The wireless communication chip 143 may be a chip configured to perform communication according to various communication standards, such as Institute of Electrical and Electronics Engineers (IEEE), Zigbee, 3rd generation (3G), 3rd generation partnership project (3GPP), or long term evolution (LTE).

The memory 150 may store various programs and data necessary for the operation of the electronic device 100. The memory 150 may be implemented as a non-volatile memory, a volatile memory, a flash memory, a hard disk drive (HDD) or a solid state drive (SDD).

The audio processor 160 is a component that performs the processing for audio data. In the audio processor 160, various processes such as decoding or amplification of audio data, noise filtering, and the like may be carried out. The audio data processed in the audio processor 160 may be output to the audio output unit 170.

The audio output unit 170 may be configured to output various notification sounds or voice messages as well as various audio data which undergone various processing operations such as decoding, amplifying, and noise filtering in the audio processor 160. Specifically, the audio output unit 170 may be implemented to be speaker; this is merely one of various embodiments of the disclosure.

FIG. 10 is a diagram illustrating an example embodiment of constructing a data recognition model through a learning algorithm and recognizing data, according to an embodiment of the disclosure.

Referring to FIG. 10, the processor 1000 according to some embodiments may include a data learning unit 1010 and a data recognition unit 1020.

The data learning unit 1010 may generate or train a data recognition model so that the data recognition model has a criterion for a service to be provided by the data recognition model or a determination of user's emotion (e.g., determination of a user's interaction and a service according to the user's interaction and determination of user's emotion regarding the user's interaction). To determine a service to be provided or user's emotion, the data learning unit 1010 may generate a data recognition model having a criterion for determination by applying learning data to a data recognition model.

For example, according to an example embodiment, the data learning unit 1010 may generate or train the data recognition model by using learning data related to voice information and learning data related to image information.

The data recognition unit 1020 may determine a service to be provided or user's emotion based on the recognition data. The data recognition unit 1020 may, using the trained data recognition model, determine a service to be provided or user's emotion from predetermined recognition data. The data recognition model 1020 may acquire predetermined recognition model according to a predetermined standard and apply the acquired recognition data as input value to the data recognition model, to thereby determine (or estimate) a service to be provided or user's emotion based on the predetermined recognition data.

In addition, an output value output by applying the acquired recognition data as an input value to the data recognition model may be used to update the data recognition model.

In particular, according to an example embodiment, the data recognition unit 1020 may apply recognition data related to voice information and recognition data related to image information as input values to the data recognition model to determine a provided service according to the recognition data.

In addition, the data recognition unit 1020 may determine the recognition data related to voice information and recognition data related to image information as information related to user's emotion.

At least a portion of the data learning unit 1010 and at least a portion of the data recognition unit 1020 may be implemented as a software module or manufactured in the form of at least one hardware, and mounted in the electronic device. For example, at least one of the data learning unit 1010 and the data recognition unit 1020 may be manufactured in the form of an exclusive hardware chip for AI, or may be manufactured as a portion of the previous general processor (e.g., CPU or application processor (AP)) or a graphic exclusive processor (e.g., graphics processing unit (GPU)), and mounted in the various electronic devices described above. In this regard, the exclusive hardware chip for AI may be an exclusive processor which is specialized in probability operation, and may show a higher performance compared with the previous general processor so as to facilitate processing of a computing operation in the field of AI such as machine learning. When the data learning unit 1010 and the data recognition unit 1020 is implemented as a software module (or a program module including a supervised), the software module may be stored in non-transitory computer readable media. In this regard, a software module may be provided by an OS or a predetermined application. Alternatively, part of the software module may be provided by an OS, and some of the at least one software module may be provided by a predetermined application.

In this case, the data learning unit 1010 and the data recognition unit 1020 may be mounted on one electronic device or on separate electronic devices, respectively. For example, one of the data learning unit 1010 and the data recognition unit 1020 may be included in the electronic device 100, and the other may be included in an external server. The data learning unit 1010 and the data recognition unit 1020 may provide the model information constructed by the data learning unit 1010 to the data recognition unit 1020 or the data input to the data recognition unit 1020 may be provided to the data learning unit 1010 as additional learning data via wire or wirelessly.

FIG. 11 is a block diagram of a data learning unit, according to an embodiment of the disclosure.

Referring to FIG. 11, the data recognition unit 1010 according to some example embodiments may include a data acquisition unit 1010-1 and a model training unit 1010-4. In addition, the data learning unit 1010 may further selectively include at least one of a pre-processor 1010-2, a learning data selector 1010-3, and a model evaluation unit 1010-5.

The data acquisition unit 1010-1 may acquire learning data necessary for learning for determining user's emotion.

For the learning data, data which is collected or tested by the data learning unit 1010 or the manufacturer of the electronic device 1010 may be used. Alternatively, the learning data may include voice data generated from a natural language uttered by the user via a microphone. Alternatively, the learning data may include image data in which the user is captured by a camera. In this case, the microphone and the camera may be provided inside the electronic device 100, but this is only an example, and voice data for a natural language acquired through an external microphone and image data for the action acquired through a camera may be used as learning data. The model training unit 1010-4 may train a data recognition model by using the learning data so that the data recognition model has a criterion for determination of a service or user's emotion. For example, the model training unit 1010-4 may train a data recognition model through supervised learning using at least a portion of the learning data as a criterion for identification. In addition, the model training unit 1010-4 may train itself using a learning data without additional instructions and train a data recognition model through unsupervised learning which discovers an identification criterion for determining a service to be provided or user's emotion.

In addition, the model training unit 1010-4 may learn a criterion for selection as to which learning data should be used to determine a service or user's emotion.

In particular, according to an example embodiment, the model training unit 1010-4 may generate or train the data recognition model by using learning data related to voice information and learning data related to image information. In this regard, when the data recognition model is trained through a supervised training scheme, as determination criteria, a service according to a user's interaction and user's emotion for the user's interaction may be added as training data.

Meanwhile, the data recognition model may be a model which is built in advance and updated by the training of the model training unit 1010-4. In this regard, the data recognition model may have received an input of basic learning data (e.g., a sample image and the like) and is in a pre-built state.

The data recognition model may be constructed considering the application field of the recognition model, the purpose of learning, or the computer performance of the device. The data recognition model may be, for example, a model based on a neural network. The data recognition model may be designed to simulate a structure of human brain on the computer. The data recognition model may include a plurality of network nodes having a weighted value which simultaneous neurons of a human neural network. Each of the plurality of network nodes may form a connection relationship so that neurons simulate a synaptic activity exchanging signals through synapse. The data recognition model may, for example, include a neuron network model or a deep learning model which is advanced from the neuron network model. A plurality of network nodes in the deep learning model may be positioned at different depths (or layers) from each other, and may exchange data according to a convolution connection relationship.

For example, a model such as deep neural network (DNN), recurrent neural network (RNN), and bidirectional recurrent deep neural network (BDNR) may be used as a data recognition model, but the disclosure is not limited thereto.

According to various embodiments, the model training unit 1010-4 may be a data recognition model for learning a data recognition model in which the input learning data and the basic learning data are highly relevant, when a plurality of pre-built data recognition models are present. In this case, the basic learning data may be pre-classified according to a data type, and the data recognition model may be pre-built for each data type. For example, the basic learning data may be pre-classified by various criteria such as an area where the learning data is generated, a time at which the learning data is generated, a size of the learning data, a genre of the learning data, a creator of the learning data, a kind of objects in learning data, etc.

Also, the model training unit 1010-4 may teach a data recognition model using, for example, a learning algorithm including an error back-propagation method or a gradient descent method.

Further, the model training unit 1010-4 may, for example, train a data recognition model through supervised learning using a determination criterion as an input value. In addition, the model training unit 1010-4 may train itself using a required learning data without additional supervisions and train a data recognition model through unsupervised learning which discovers an identification criterion for determining a service to be provided or user's emotion. Further, the model training unit 1010-4 may teach the data recognition model through reinforcement learning using, for example, feedback as to whether a result of the judgment based on learning is correct.

In addition, when the data recognition model is trained, the model training unit 1010-4 may store the trained data recognition model. In this regard, the model training unit 1010-4 may store the trained data recognition model in the memory 110 of the electronic device 100. Alternatively, the model training unit 1010-4 may store the trained data recognition model in a memory of a server connected to the electronic device 100 via a wired or wireless network.

The data learning unit 1010 may further include a pre-processor 1010-2 and a learning data selector 131-3 to improve a recognition result of the data recognition model or to save resources or time required for generating the data recognition model.

The pre-processor 1010-2 may preprocess data acquired from the data acquisition portion 1010-1 to use the data for learning to determine a service to be provided or user's emotion.

For example, the pre-processor 1010-2 may process the acquired data in a predefined format so that it is easy to use the data for learning of the data recognition model. For example, the pre-processor 1010-2 may process a voice data acquired by the data acquisition unit 1010-1 into text data, and process the image data into image data of a predetermined format. The preprocessed data may be provided to the model training unit 1010-4 as learning data.

Alternatively, the learning data selector 1010-3 may selectively select learning data required for learning from among the preprocessed data. The selected learning data may be provided to the model training unit 1010-4. The learning data selector 1010-3 may select learning data required for learning from among the preprocessed data according to a predetermined criterion of selection. In addition, the learning data selector 1010-3 may select learning data required for learning according to a predetermined selection criterion by learning of the model training unit 1010-4. In one example embodiment of the disclosure, the learning data selector 1010-3 may select only voice data that has been uttered by a specific user among the input voice data, and may select only a region of the image data excluding the background.

The data training unit 1010 may further include a model evaluation unit 1010-5 to improve a recognition result of the data recognition model.

The model evaluation unit 1010-5 inputs evaluation data to the data recognition model, and when a recognition result output from the evaluation data does not satisfy a predetermined criterion, the model evaluation unit 1010-5 may instruct the model training unit 1010-4 to train again. In this case, the evaluation data may be predefined data for evaluating the data recognition model.

For example, if the number or the ratio of the evaluation data whose recognition result is not accurate among the recognition results of the learned data recognition model for the evaluation data exceeds a predetermined threshold value, the model evaluation unit 131-5 may evaluate that predetermined criteria are not satisfied. For example, in the case where a predetermined criterion is defined as a ratio of 2%, when the learned data recognition model outputs an incorrect recognition result for evaluation data exceeding 20 out of a total of 1000 evaluation data, the model evaluation unit 1010-5 may evaluate that the learned data recognition model is not suitable.

On the other hand, when there are a plurality of learned data recognition models, the model evaluation unit 1010-5 may evaluate whether each of the trained data recognition models satisfies a predetermined criterion, and determine a model satisfying the predetermined criterion as a final data recognition model. In this case, when there are a plurality of models satisfying a predetermined criterion, the model evaluation unit 1010-5 may determine any one or a predetermined number of models previously set in descending order of an evaluation score as a final data recognition model.

At least one of the data acquisition unit 1010-1, the preprocessing portion 1010-2, the learning data selector 1010-3, the model training unit 1010-4, and the model evaluation unit 1010-1 may be implemented as a hardware chip or may be manufactured in the form of a hardware chip and mounted on an electronic device.
